NOCO HM484 8D Commercial-Grade Battery Box

Liked size and price. Built strong and rust proof.Unfortunately just to big for my available location.

Heavy duty. Quality. But it was too big to fit in this area. So we had to return. Not products fault.

We had recently purchased a 200ah Lithium Battery to replace the aging 6v batteries on our Travel Trailer. This battery was physically wider than the 6v units, and no conventional "dual" SLA Battery Boxes would contain this unit. Having originally strapped the battery to the front of the trailer, I was immediately concerned with curious eyes and sticky fingers. I knew a battery box would be required, not necessarily for elemental protection, but to conceal.The battery we purchased was a standard Group 8D size, and while a tight fit in the stock battery location, it did fit with plenty of spare room. The main issue I have with this box, and the reason for knocking a star off, is it is simply over-sized.That's not usually a huge problem, but trailers are designed to be in motion, and you don't really want your battery sliding around, even if it's inside a box meant to contain it. I didn't spend a lot of time trying to see if I could strap the battery down inside, but there was nothing I saw that was obvious. Instead, I used a couple of foam packing "boards" to stuff into the sides of the box and keep the battery from moving.The next issue was the box was so large, it had to be assembled, battery and all, before being set into the battery tray. This meant I couldn't even properly screw it into the battery tray. The space is so tight, that I can't even remove the lid. And while it would be physically impossible to remove the battery without first unbolting everything off the front of the trailer, I used a ratchet strap to be extra secure. Granted, you may not have this issue as every trailer is different. I feel I got lucky and the box "just" fit.The box itself is very sturdy, and I thought the battery cable pass through locations were perfect. The lid has rubber grommets to help seal against water intrusion. It was the most affordable 8D solution I could find. Just make sure you are aware of the sizing issues.

These storage boxes are very well constructed and very spacious. My two new LiFePo4 house batteries will be well protected inside of them. The lids are nice and secure too.

4x100AH Lifepo4 batteries. 2xWattcyle minis and 2xregualr size batteries. Tight fit but got the job done!

Fit perfectly in the back of my Colorado a strap to strap it to the front of the truck works perfect and my tonneau cover goes over it!

I installed this on my camper tongue between the body and the propane bottles. Installation was easy, very clean and am really happy with the end result.

I bought this for my RV travel trailer so that I could upgrade to a bigger battery size. The box arrived, and I was super impressed at the quality and build. It is a tank and it is well worth the money. So why only 4 stars? Well, it was too big, and the way the box is built, it is tapered and bigger at the base than at the top. Also, the four corners have protruded bolt down points that would not handle very much pressure. If you tightened it down just a little too much, it would break off. Also, there is no seal around the top of the box, or around the lid to keep out water and dirt.Other than that, this is a perfect box. Unfortunately I had to return it as it was too big and I could not bolt it down on my trailer tongue. I would have to modify it too much to get it to work. Still, 4 stars from me!
